摘要： A swash plate tiltably supported on a drive shaft is controlled by adjusting the pressure in a crank chamber. When an electromagnetic valve is de-excited, the high-pressure refrigerant gas in a discharge chamber is supplied to the crank chamber so that the inclination angle of the swash plate is shifted to its minimum inclination from its maximum inclination. An open/close mechanism located in a suction passage gradually opens or closes the suction passage in accordance with the differential pressure between the pressure in the external refrigeration circuit located upstream the open/close mechanism and the pressure in a suction chamber. When the inclination angle of the swash plate is minimized, the open/close mechanism closes the suction passage. It is therefore possible to prevent frosting while also suppressing rapid changes in load torque.

摘要： A control valve for a variable displacement compressor in refrigerant circuit permits the compressor displacement to be accurately controlled regardless of the thermal load on an evaporator. The refrigerant circuit includes a high pressure pipe, which extends between a discharge chamber of the compressor and a condenser. A first pressure monitoring point is located in the discharge chamber. A second pressure monitoring point is located in the high pressure pipe. A supply passage connects the second pressure monitoring point with a crank chamber of the compressor. The control valve is located in the supply passage and adjusts the opening size of the supply passage in accordance with the difference between the pressure at the first pressure monitoring point and the pressure at the second pressure monitoring point. The control valve includes a solenoid for determining the target value of the pressure difference. The control valve operates to maintain the determined target value.

摘要： An air conditioner having a refrigerant circuit that maintains a high cooling efficiency and a sufficient amount of oil returned to a compressor even if the flow rate of refrigerant is decreased due to a low cooling load is provided. The refrigerant circuit includes a condenser, an expansion valve, an evaporator and a variable displacement compressor. The expansion valve is normal-charge type. A control valve adjusts the pressure in a crank chamber based on the value of a current from a controller and on a pressure difference between two pressure monitoring points, which are located in the refrigerant circuit. Accordingly, the compressor displacement and the flow rate of refrigerant in the circuit are controlled.

摘要： A variable displacement type compressor in which a discharge-pressure region, a suction-pressure region and a pressure control chamber are defined, has a tiltable swash plate and a piston reciprocated by the swash plate in the pressure control chamber. The inclination angle of the swash plate and the piston stroke are changed by adjustment of pressure in the pressure control chamber thereby to control the displacement of the compressor. The compressor further comprises a supply passage for supplying refrigerant gas from the discharge-pressure region to the pressure control chamber, a release passage for releasing the refrigerant gas from the pressure control chamber to the suction-pressure region, a first control valve for adjusting a cross-sectional area of the supply passage from the discharge-pressure region to the pressure control chamber and a second control valve for adjusting cross-sectional area of the release passage. The second control valve includes a valve body for opening and closing the release passage whose cross-sectional area is set minimum when the valve body is located at the closed position and a valve spring for urging the valve body in a direction to open the release passage. When the second control valve is closed, pressure in the supply passage downstream the first control valve acts on the valve body in a direction to close the release passage and pressure in the suction-pressure region acts on the valve body in a direction to open the release passage.
